Effect of aphid species infestation on wheat crop, Triticum aestivum L. and its yield.

Among cereal crops, wheat (Triticum aestivum L.) is an important staple food for human. Rhopalosiphum maidis, Rhopalosiphum padi, Schizaphis graminum and Sitobian avenae are the major aphid species of wheat in Pakistan, which cause huge yield losses in wheat crop. The study was conducted to check the effect of aphid density on wheat crop and its yield. Our observation was made from heading to early-dough stage. Mean spike length, number of grains per spike, 100 grains weight and yield kg/ha was significantly affected by the population density of an aphids. Aphid density was low correlated with mean spike length but it was significantly correlated with number of grains per spike, 100 grains weight and yield kg per hectare.
